Conveyor apparatus for discharging pressed products and similar items from a press

Abstract

An apparatus for conveying and discharging pressed products or similar items from a press. The apparatus has a discharging trough which can be mounted on a portion of the body of the press, and a reciprocating member for causing a reciprocatory motion of the discharging trough. The reciprocating member is driven by a driving mechanism so as to make such an action that a difference exists between the forward moving speed and the backward moving speed, thereby allowing the discharge of the pressed products or similar items along the discharging trough.

What is claimed is: 
     
       1. Apparatus for conveying and discharging production and scrap products from a press (23), said apparatus comprising: an elongated discharging trough (21);   a reciprocating member (9) operatively connected to said trough to drive the latter reciprocatively generally parallel to its longitudinal axis;   a driving mechanism operatively connected to said reciprocating member to drive the latter forward and backward with a reciprocatory action that provides a substantial difference in speed between forward and backward movement of said member whereby products loaded into said trough are discharged through an opening at its front end;   said driving mechanism including a cam (6) having a generally S-shaped camming surface (6d, 6e) rotatable on a rotational axis (5) that is generally perpendicular to said longitudinal axis, a cam follower (13) mounted on said reciprocating member, biasing means (11) urging said follower toward said camming surface whereby said cam drives said reciprocating member rearward during a first portion of a rotation cycle for said cam;   said camming surface being shaped to separate from said follower during a second portion of said cycle and permit said biasing means to drive said reciprocating member forward, with speed of forward motion for said reciprocating member exceeding its rearward speed.   
     
     
       2. An apparatus for conveying and discharging production and scrap products from a press according to claim 1, wherein said discharging trough (21) is mounted at an inclination such that the front end of said trough is held at a lower level than its rear end. 
     
     
       3. An apparatus for conveying and discharging production and scrap products from a press according to claim 1, further comprising an adjusting means for adjusting at least one position of height and inclination positions for said discharging trough. 
     
     
       4. An apparatus for conveying and discharging production and scrap products from a press according to claim 3, wherein said adjusting means also includes a mounting member (19) secured to said reciprocating member (9) and supporting said discharging trough (21), a pair of bolts (20a, 20b) extending through said mounting member (19) and driven into said reciprocating member (9) at a selected position heightwise, and a hole (19e) formed in said mounting member (19) such as to allow one (20b) of said bolts (20a, 20b) to pass therethrough, said hole (19e) allowing said mounting member (19) to pivot about the other bolt (20a) as a center. 
     
     
       5. An apparatus for conveying and discharging production and scrap products from a press according to claim 1, wherein said cam (6) is composed of a plurality of cam segments stacked and fixed in layers so as to have a considerable thickness. 
     
     
       6. An apparatus for conveying and discharging production and scrap products from a press according to claim 1, further comprising a supporting frame (2) for supporting said reciprocating member (9), said supporting frame (2) having first and third pins (38, 58) spaced in the vertical direction and adapted to guide said reciprocating member in the horizontal direction, said biasing means comprising first and second coiled springs (11) mounted on individual ones of said first and third guide pines, each of said guide first and third pins having a formation (38a, 58a), one end of each of said coiled springs engaging individual ones of said formations and the other ends of said coiled springs engaging with a portion (9a) of said reciprocating member (9). 
     
     
       7. An apparatus for conveying and discharging production and scraps products from a press according to claim 6, wherein said supporting frame (2) further includes a second guide pin (48) between said first and third guide pins (38, 58), said second guide pin (48) supporting a coiled spring (12) which is adapted to be engaged with a portion of said reciprocating member (9) during forward movement of said reciprocating member (9), thereby reducing the impact of said reciprocating member (9).
